Spliced and Vulcanized o-rings are custom sized o-rings made for any application. Spliced and Vulcanized o-rings are great for custom design or a unique size that is not included on the standard charts. Spliced and Vulcanized o-rings are a viable solution when standard o-rings cannot be used.
Vulcanization is a process which used heat, rubber adhesive, pressure and time to chemically bind the two ends together. The o-ring cord is cut to order, and vulcanized to ensure the strength of the joint. Spliced o-rings are made from extruded o-ring cord and then vulcanized to form the o-ring size using ID, OD or cut-length required. There are a variety of joints which can be bonded.
Applications such as window frame gaskets, door gaskets, filter housing gaskets and lid gaskets. The uses are as unlimited as your imagination will allow. A spliced and vulcanized o-ring must be used in static applications. Static seals are a seal that is made between two stable and immovable components.
The splice is usually never as strong as the original material from which the gasket is made. The doubling over, pinching and the twisting of a splice or bending back on a corner splice are not proper methods of testing.
